Dragon King: Key to Nantianmen

Three thousand years ago, Haichen, the Dragon Lord of the North Sea, was betrayed by his beloved Nita Luo, and his soul was shattered and died in the depths of the clouds. Three thousand years later, he woke up in the modern city, his dragon soul rekindled, and a Tianmen seal locked in his body to block the world-destroying flood. The flood will break through the seal and pour into the world within seven days. Only if he personally opens the Nantian Gate and directs the torrent into the East China Sea can he save the people. But once the Heavenly Gate is opened, all the demons and monsters that have been suppressed for thousands of years will return to the Three Realms. The Emperor of Heaven ordered him to stick to the seal and sacrifice the mortal world to protect the heaven; his old love appeared and persuaded him to put down his obsession and live alone. All living beings in the three realms regard him as the biggest variable that stirs up the world. Looking at the surging waves that destroyed the world, Haichen held tightly the ancient fuso tree with three cracked lines and smiled softly. When the road of heaven is cut off, I will open the gate of heaven for the common people. A demon is born? I just press them back one by one! He is an abandoned son of heaven, but he has to be the only chess player in this world-destroying death game.
